[Experimental] Install W10 on ANY phone running 8.1

There's a reason why it's not released for higher end phones. In my mind, MS doesn't want to brick expensive phones. :)
Anyways, my friend who updated his 630 to Win 10 just reset back his phone to factory settings. A lot of stuffs are not working yet on 10.
In short, nobody is missing anything. Just continue using Win 8.1.

it's not about brick the phone,ms just want user for higher end device bussy to reinstall their phone before they can install the preview ;)

That's where it says the device (whose name really is "Phone in flash mode", system device name "QHSUSB_DLOAD", and description "Nokia Emergency Connectivity") is unsupported.

Sorry bro but thats the sign of a completely bricked device it can only be solve by using riff box j-tag method
That usually occurs when you are trying to flash your device and the usb cable gets disconnected or get loose cause of this the bootloader of the device gets corrupted if it is in warranty i would advice you to take it to service center for repair

1. Install the Windows Insider app on your phone
2. .............

7. Tap on the link at the bottom to the fiddler root certificate
8. When prompted click open and then install to trust the cert and ok at the confirmation
9. Run the Windows Insider app and tap get preview builds
10. Tap on which custom action youd like to perform. In my case I hit "Set to ATT Lumia 635" and click the arrow at the bottom
11. Accept the agreement and click the check mark at the bottom. the app will close
12. run the insider app again, click get preview build login with your Microsoft account if require (in this case you will see 'insider slow' and 'insider fast') don't choose anyone of them press home or toggle Setting from the notification and disable proxy then switch back to the Windows Insider app the choose either one of them ( 'insider slow' and 'insider fast')
13. Go into the phone settings and check for updates. With any luck you should have Windows 10 there for you to install.

I tried fiddler root certificate, after end off step 11 U say app will close, my 930 has to reboot

It doesnt matter if its hk or gb or anyother.
If product code is of device eligible then you will get update.
It just make the server thinks your device is an eligible device for update.
Nothing else.
you can reset your device normally by going in about section not via lsrt to get your original info back

So how can you get cellular data running? Even using the settings from the carrier's website doesn't help. Also none of the keyboards can be downloaded.

ok for anyone trying this approach make sure you are not running anything later than 02540.00019.14484.xxxxx for the firmware on your phone. the insider program has a bug with any 8.1 firmware higher than this, so no matter how hard you try if its higher than that nothing will show for updates. I have tested this bug on my 1520 and 930 that were running firmware higher than what I said above. I reflashed to a lower firmware and no issues installing the TP10.

Hey, I have also installed the TP on my 1020 (India, airtel). For some unknown reason after I did a hard reset, my internet connection from my carrier has stopped working. In Access Point it says " INACTIVE : There may be a problem with access point settings, Restarting your phone may fix it ", but still no luck. Has anyone else encountered this problem and is there any solution to it ?

ohh god,i think you are right about this one,i flash my 1520 with this firmware,nothing problem during the process to installing the preview,but the problems come after my device running the preview,for example,on ie,i can't save any pictures, i can change the background image atleast after 4 time crash, scrolling start menu is not really smooth and feels like using win phone 8 launcher on androud device. before i read your post,i guess it's normal for this preview,but thks,trying to reflash now and start from beginning EDIT: My question,how we can find a lower firmware on WPRT or LSRT? cz from my experience,both software give me the update firmware automatically,,i need your help.. ;)

OOKKK GUYS
it's really the problem ... I tried like 10 things today. The problem was that after I hard reset with LSRT, I received the last update (14522) but if you have something after 14484, the phone don't see new update. I rolled back to a french rom with 14484 and my phone install the update right now.

I had problem with the start screen ( I'll update if it's better) and I was not able to install new keyboard.

I don't know if you want to know the problem with the screen or the update. I'll ask both.
1st : After install the clean os with LSRT (rom 14522) I wasn't able to install the WTP. With the 14484 (it's installing right now)
2nd : for the start screen (it was yesterday) with the Technical preview. I wanted to do a clean install because I saw in another thread that it solved the problem.
for the problem with the keyboard with a french rom ( I'll have french (france) keyboard, but not French (canada) ) but it's better than nothing. (maybe I'll be able to install it).

edit : OK I seems to have the same screen lag than I had. I'm doing the hard reset so my phone will have the good name product in it ( for futur update or firmware update ) and put my backup in it at the same time.

I think I'll live with the problems I have and when the original update or future update if I need I'll hard reset again.

SAme here, yesterday I was finally able to install TP, i had to flash poland cyan rom to get this done, but after update I cant install my native language keyboard and sometimes the keyboard has that weird bug, when there is ENTER all over keyboard :D

Does anybody know, where eventually find older firmware, but exactly for your phone? I know about seidea site, but that site does not open for me :)
